Description

Portable magnet, common battery, automatic telephone set

The utility model relates to a kind of improved pocket telephone, and it can be common to magnetite, common-battery and make on the communication line automatically.

Wire telephone is divided into magnetite, common-battery and makes three kinds automatically, and they are applicable to respectively on the communication line of its corresponding standard.The telephone set of general manufacturer production and sale all is a single system usually, and at many existing local telephone networks the area of farm work is arranged, and in the electrical communication system of army, exists the communication line of several standards simultaneously.Therefore, phone user or communication equipment line maintenance personal only use the telephone set of single system, just very inconvenient work.

The purpose of this utility model is that a kind of improved pocket telephone will be provided, it can be common to magnetite, common-battery easily and make automatically on the communication line, is suitable for army's communication, construction project temporary erection phone and machine line maintenance personal line walking to look into the usefulness of repairing especially.

The utility model is achieved in that on the portable local battery apparatuses of square-box shape such as 65 types or HCX type, installs dial, switch, electric capacity, resistance and a hold-in winding respectively additional.Dial is used for making on the circuit automatically posting a letter, switch is used for common-battery and converses and Waiting for Call control on the system circuit automatically, electric capacity is used to cut off DC channel, and resistance is used for being engaged in when dialing antispark with electric capacity, and hold-in winding is used for keeping linking up common-battery, unattended station DC circuit.According to the design's requirement, install said elements additional, on the original words machine circuit, carry out local reconfiguration, local battery apparatus is used on common-battery and the automatic system communication line, reach a tractor serves several purposes.

The utility model, make easily, and cost is low so circuit is simple because only need to install the minority element additional on former portable local battery apparatus.In addition, the utility model can not only keep former machine performance, and when being used for common-battery and making circuit automatically, phone send the words current stabilization, is not subjected to the influence of intra-office power supply and outside line loop resistance.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is a basic circuit schematic diagram of the present utility model.

Fig. 2 is surface structure form figure of the present utility model.

With reference to Fig. 1: be the element that installs additional in the frame of broken lines, wherein dial is the C-19AM1 type, resistance R ₁Be 330 ohm, capacitor C ₁Be 1 microfarad, K switch is two cuttves, two throw switches, and hold-in winding IC is the individual pen ring coil, and its D.C. resistance is 400～800 ohm.If do not insert the above-mentioned element that installs additional, binding post X ₂With electric bell DL, capacitor C ₂And button AJ ₁Directly link to each other, this machine is typical portable local battery apparatus.Its signal circuit adopts short circuit not ring the series connection of holding concurrently from the bell ring circuit from bell, and speaking circuit adopts twin coil bridge-type anti-side-tone circuit, and signal circuit and speaking circuit are to carry out electric separating with electric capacity.The utility model is to open binding post X in former local battery apparatus line interruption ₂With electric bell DL, capacitor C ₂And button AJ ₁Between line, 1 end of K switch is connected binding post X ₂, 4 ends of K switch merge with 2,3 ends of dial and are connected electric bell DL, capacitor C ₂And button AJ ₁Point in parallel, 1 end of dial connects 2 ends of K switch, 4 ends of dial connect binding post X ₁, hold-in winding IC two ends connect 5 ends of K switch and the merging point of electric bell DL and generator, resistance R respectively ₁Two ends connect 4 ends and 6 ends of K switch, capacitor C respectively ₁Two ends connect 1 end and 6 ends of K switch respectively.As follows to the utility model circuit working procedure declaration below:

1, at common-battery with make on the circuit automatically and use

(1) collection of letters circuit: K switch is in " wait " position at ordinary times, ringing-current is imported through following loop, electric bell is rung: telephone exchange-outside line X ₁-generator reed 3,2-electric bell DL-K switch 4, the 6-capacitor C ₁-outside line X ₂-telephone exchange.

(2) transmitting circuit: use on the common-battery system circuit, K switch is in " conversation " position, has promptly connected the DC circuit of posting a letter: telephone exchange-outside line X ₁-generator reed 3,2

Impulse contact MD-K switch 2,1-outside line X ₂-telephone exchange.If using on the system circuit automatically, at first the same with the use of common-battery system circuit, connect telephone exchange's DC circuit, in earphone, hear dialing tone, press the called number dial again, pulse current is sent through following loop: telephone exchange-outside line X ₁-shunt contact DD-impulse contact MD-K switch 2,1-outside line X ₂-telephone exchange.In addition, when the Sending dialled number pulse, capacitor C ₁And resistance R ₁Be connected across between the impulse contact, play the antispark effect.

(3) originating circuit: K switch is in " conversation " position, holds down mobile phone and holds key AJ ₂, connected the transmitter local circuit: battery DC ₊The T of-coil Q, A-hold key AJ ₂-transmitter S-battery DC _-At this moment, words stream output circuit is as follows: the B end-generator reed 2 of coil Q, 3-outside line X ₁-the other side-outside line X ₂-K switch 1,2-impulse contact MD-capacitor C ₂The P end of-balancing network-coil Q.

(4) PAC circuit: K switch is in " conversation " position, and words stream input circuit is as follows: the other side-outside line X ₁B end-receiver SH-the capacitor C of-generator reed 3,2-coil Q ₂-impulse contact MD-K switch 2,1-outside line X ₂-the other side.

2, on the magneto system circuit, use

(1) collection of letters circuit: K switch is in " wait " position, and its circuit is identical with use on common-battery and automatic system circuit.If K switch is in " conversation " position, also can collects mail, but, will have a strong impact on and receive bell sensitivity because hold-in winding is connected in parallel on the ring coil two ends.

(2) transmitting circuit: it still is that " wait " position is all passable that K switch is in " conversation ", and when the rocking-turn generator, ringing-current is exported through following loop: the 3-outside line X of generator ₁-the other side-outside line X ₂-capacitor C ₁With K switch 6,1,2 and impulse contact MD of 4(or K switch)-test button AJ ₁-generator reed 1,2.
